  • A general approach for computing residues of partial-fraction expansion of transfer matrices 

    García Planas, María Isabel; Domínguez García, José Luís (2013-07)
    Article
    Open Access
    This paper deals with the description of a general method for calculating the residues of a linear system. Considering, physical models, it is well-assumed that the system described only presents simple eigenvalues, or at ...
  • Alternative tests for functional and pointwise output-controllability of linear time-invariant systems 

    García Planas, María Isabel; Domínguez García, José Luís (2013)
    Article
    Open Access
    This paper deals with the description of a new method for calculating the functional output-controllability. It is computed by means of the rank of a certain constant matrix which can be associated to the system. Moreover, ...
  • Analysis of support structure of wind turbine tower 

    Mediano Valiente, Begoña; Domínguez García, José Luís; García Planas, María Isabel (2013)
    Conference report
    Open Access
    Wind turbines are being used to generate electricity as an alternative energy source to conventional fossil fu- els, and it is well known that wind towers must to sus- tain continuous vibration forces throughout their ...
  • Control signal selection for damping oscillations with wind power plants based on fundamental limitations 

    Domínguez García, José Luís; Bianchi, Fernando Daniel; Gomis Bellmunt, Oriol (2013-11)
    Article
    Restricted access - publisher's policy
    Transmission system operators are increasingly demanding that wind power plants (WPPs) contribute to enhance stability of power systems. When WPPs act as power system stabilizers(PSSs), the control and measured signals ...
  • Experimental validation of a real-time energy management system using multi-period gravitational search algorithm for microgrids in islanded mode 

    Marzband, Mousa; Ghadimi, Majid; Sumper, Andreas; Domínguez García, José Luís (2014-09-01)
    Article
    Open Access
    Both performance optimization and scheduling of the distributed generation (DG) are relevant implementing an energy management system (EMS) within Microgrid (MG). Furthermore, optimization methods need to be applied to ...
  • Functional output-controllability analysis of fixed speed wind turbine 

    Domínguez García, José Luís; García Planas, María Isabel (2013)
    Conference report
    Open Access
    This paper deals with the concepts of functional output-controllability character of a finite-dimensional linear dynamical system. And a method for comput- ing the functional outputcontrollability consisting on the ...
  • Input Observability Analysis of Fixed Speed Wind Turbine 

    García Planas, María Isabel; Domínguez García, José Luís; Mediano Valiente, Begoña (WSEAS Press, 2012-04)
    Part of book or chapter of book
    Open Access
    This paper deals with the concept of input observability in a fixed speed wind turbine. A linear system has been calculated from the nonlinear equations of the squirrel cage induction generator, supposing it connected directly ...
  • Output controllability analysis of fixed speed wind turbine 

    Domínguez García, José Luís; García Planas, María Isabel (2011-09-05)
    External research report
    Open Access
    This paper deals with a study of output-controllability of a squirrel cage induction generator connected directly to grid. To obtain the Linear Time Invariant System, which describes the generator behavior, are chosen the ...
  • Output controllability analysis of fixed speed wind turbine 

    Domínguez García, José Luís; García Planas, María Isabel (2011)
    Conference report
    Open Access
    This paper deals with the concepts of output controllability and steady output controllability, it demonstrates that they are not equivalent of concepts. A linear system has been calculated from the nonlinear equations of ...
  • Power system stabiliser capability of offshore wind power plants 

    Domínguez García, José Luís; Gomis Bellmunt, Oriol; Bianchi, Fernando Daniel; Sumper, Andreas; Sudrià Andreu, Antoni (2012)
    Conference lecture
    Open Access
    Nowadays, wind power generation is being located offshore because of its higher wind speed at lower height and larger installation zones in comparison with onshore technologies. Recently, the concept of wind power plant ...
  • Power system stabilizer control for wind power to enhance power system stability 

    Domínguez García, José Luís; Gomis Bellmunt, Oriol; Bianchi, Fernando Daniel; Sumper, Andreas (2011)
    Conference lecture
    Open Access
    The paper presents a small signal stability analysis for power systems with wind farm interaction. Power systems have damping oscillation modes that can be excited by disturbance or fault in the grid. The power converters ...
